Advanced thermal chemical conversion process of municipal solid waste
11584893 · 2023-02-21 · ·

A method of processing MSW, either sorted or unsorted, which can be carried out through the use of canisters to hold the waste feedstock, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The final solid product is a mixture of carbon ash and non-combustible materials, such as, metals, drywall, etc., and syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft.sup.3. The remainder solid material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.

Furnace floor protection in recovery boilers
11274824 · 2022-03-15 · ·

A method and apparatus for protecting a furnace floor of a black liquor recovery boiler, where a mixture is formed by mixing material with a fluid, and the furnace floor is covered by said mixture by flowing the formed mixture onto the floor from the outside of the furnace.

UPDRAFT GASIFIER AND METHOD, APPARATUS, AND SYSTEM FOR BIOMASS DECOMPOSITION

A method, system, and apparatus for decomposing a biomass feedstock include providing a layer of inert particulate matter, such as sand, to line and insulate the bottom surface of a main chamber of a reactor where pyrolysis and oxidation are conducted to produce char and producer gases as primary products. In an embodiment, feedstock positioned in a side region of the reaction chamber insulates side walls of the main chamber from heat in the center region of the main chamber. In an embodiment of the method, a rate of removal of solid products such as char from the reactor is controlled in response to a temperature detected at a position of an extraction tube inlet of the reactor. Activated charcoal may be obtained as a primary product using the system and method, by feeding oxygen into the reactor at an inlet positioned adjacent to an inlet to the extraction chamber.

Reactor for the advanced thermal chemical conversion processing of municipal solid waste
11098251 · 2021-08-24 ·

A reactor system made up of a single canister or a plurality of separate canister sections for the advanced thermal chemical conversion processing of municipal solid waste (“MSW”), either sorted or unsorted, and autoclaves specially designed to process the waste at suitable temperature and pressure combinations is disclosed. The canister sections can be individually and separately filled with compressed bales of MSW or with selected loose MSW. The reactor system can produce syngas that has an enhanced BTU value, typically between about 300 to 700 BTU/ft.sup.3. The remainder solid waste material generally amounts to approximately 5% of the original MSW volume. This material can then be sorted for metals with the balance being sent to a landfill or other recycling processes depending on its composition.
